Nasturtium Baby Rose brings warm rose-pink flowers and round blue-green leaves to sunny spots through late summer and into fall. Sow direct in poor soil—it actually flowers better when you don't fuss with fertility—and watch it sprawl or climb depending on where you tuck it.

Heat and drought won't slow it down once it's rooted, and the whole plant is edible if you want to toss petals and peppery leaves into a salad. Thrives in containers or garden beds that get at least six hours of sun.
